DropDown items undefined after postback

Question

Hi,I've update controls from 14.2451.0.28 to  14.4.0.20.In first load, al dropdowns load perfect, but after a postback, the dorp down items are undefined.I tried reproduce this error with the Sample creator, and I couln't do it. But in my application it works wrong. I return to version 14.2451.0.28 and all works fine.Any idea?Thanks
